Description
Technical field
The utility model belongs to electrical engineering technology, and in particular to a kind of direct current cables.
Background technique
New more than 100 kilo-amperes of HL-2M tockmark electric current, power-supply system are all made of the pulse direct current method of operation and use
Cable is transmitted electricity as conductor to device, and cable passage is cable tunnel, cable bearer gantry or poling.Currently, non-high pressure is straight
Stream transmission of electricity generally uses single or two core cable, is partially replaced with ac cable, such as current-carrying capacity or insulation in the selection of parameter
It is different with ac cable on thickness degree, than if you need to consider skin effect and field distribution.And single or two core cable are big
The pulse of current DC transmission of electricity or high current need power supply or equipment to be frequently necessary to existing defects under the operating condition of on-off, above
In the case of, intensive cable is laid in cable tunnel can generate galvanomagnetic-effect, such as generate inductive loop to metal, generate between conductor
Electric power etc., or even all have an impact to the close intracorporal reinforcing bar of building.
Summary of the invention
The purpose of the utility model is to provide a kind of direct current quads for high current transmission of electricity, can eliminate major part
Electromagnetic radiation and galvanomagnetic-effect.
The technical solution of the utility model is as follows:
A kind of direct current quad for high current transmission of electricity, including four cable core conductors in shielded layer and shielded layer,
Insulating layer is equipped with outside four cable core conductors, one group of diagonal cable core conductor is same pole.
The colour code of same color is equipped with outside insulating layer outside diagonal cable core conductor.
Four cable core conductors form four core conductor structure of cross-section, i.e. four cable core conductors are in close contact, and arrange in quadrangle.
Cable cover(ing) is enclosed on the outside of the shielded layer.
The colour code is the mark being attached to outside cable core insulating layer, and it is axial to penetrate through whole cable.
The beneficial effects of the utility model are as follows: the diagonal core electric current of cable is contrary, and magnetic potential vector mutually supports
Disappear, electric power between conducting wire when reducing high current transmission of electricity；When electric current quickly changes, induced electromotive force is reduced to surrounding shield
Fever and the loss of power caused by circulation caused by the metallic conductors such as layer, fitting or vortex.
Detailed description of the invention
Fig. 1 is the direct current quad transmitted electricity for high current；
In figure: 1. cable core conductors, 2. insulating layers, 3. colour codes, 4. cable cover(ing)s, 5. shielded layers.
Specific embodiment
Below by the drawings and the specific embodiments, the utility model is described in further detail.
The direct current quad of high current transmission of electricity is made of four cable core conductors 1 in shielded layer 5 and shielded layer 5.
Every the external of cable core conductor 1 wraps up insulating layer 2, and insulating materials is crosslinked polyethylene, polyethylene or polychlorostyrene second
Alkene.
Four cable core conductors 1 form four core conductor structure of cross-section, i.e. it is in quadrangle cloth that four cable core conductors 1, which are in close contact,
It sets, diagonal cable core conductor is same pole and the colour code 3 of same color indicates outside insulating layer 2.
The effect of colour code 3 is the direct current positive and negative anodes for distinguishing connection equipment, same when cable is connect with electrical equipment
The cable core conductor 1 of kind colour code connects the same pole of direct current, for example red connects anode, and blue connects cathode.
Using four core conductor structure of section, the current direction in diagonal cable core conductor 1 in cable is on the contrary, its effect is
Magnetic potential is set to cancel out each other, electric power between conducting wire, reduces the induction electric generated when electric current quickly changes when reducing high current operation
Gesture is to circulation or vortex caused by surrounding shield layer, fitting etc. nearby metallic conductor.
Cable cover(ing) 4 is enclosed on the outside of shielded layer 5.
The materials such as the cable core conductor 1 of cable described above, insulating layer 2, shielded layer 5, cable cover(ing) 4 are referring to existing friendship
Galvanic electricity cable.
Above-described colour code 3 is the mark being attached to outside cable core insulating layer, penetrates through whole cable axial direction, colour code can
To be the word or symbol of printing, it is also possible to the colour bar of adherency or the insulating layer using different colours, colour bar is using non magnetic
Material.
The diagonal core electric current of cable is contrary, and magnetic potential vector is cancelled out each other, and reduces conducting wire when high current transmission of electricity
Between electric power；When electric current quickly changes, induced electromotive force is reduced to ring caused by the metallic conductors such as surrounding shield layer, fitting
Fever and the loss of power caused by stream or vortex.
